The Westminster Kennel Club Dog Show has gotten underway, welcoming new dog breeds and challenging dogs and their human companions to tests of agility and much more.

This year's winner of the agility contest was Holster, an Australian shepherd from Greenwich, New York. Holster and his handler, Wendy Cerilli, completed the course in 35.10 seconds, well ahead of their nearest competitors. Two different border collies had previously won The Masters Agility Championship, which was added to the competition in 2014, so this makes Holster the first Aussie to win the championship.
